Hazards of Aluminium welding fume

Electric welding was introduced in 1940s. Aluminium welding has been in prominence since 1970. There are several types of welding like Arc welding and Manual metal arc is a common process where the workers are exposed to the fumes. Carbon arc, Cold welding, Electron beam welding, Flux core arc welding, Gas welding, Gas metal arc welding, Gas tungsten arc welding, Shielded metal arc welding, Plasma arc welding, Laser beam welding are the other welding processes where workers are exposed to metal fumes.
The welding workers have a high exposure of metal fumes and the exposure depends on place, confined space, workshop or open air. The metal fumes depend on not only the Aluminium but also the process involved which may produce gases like acetylene, carbon monoxide, oxides of nitrogen , ozone, phosgene and tungsten. The metal fumes primarily enter the human system by inhalation route namely Respiration.. The deposition of these inhaled metallic particles is influenced by its physical and chemical properties and a variety of host factors. In the lungs, these particles produce a variety of reactions depending on the concentration, duration of the exposure of the particles, and degree of exposure. ...Show more

Summary
